A lightweight and easy-to-use Python tool to convert .mat (MATLAB) files into .jpg image files. Useful for data preprocessing, machine learning pipelines, or visualization purposes.

📌 Features

• Converts 2D .mat arrays into .jpg images
• Batch processing support
• Custom output directory
• Normalizes pixel values (0–255)
• CLI-based usage for ease of automation

📂 Example

Input .mat file:

Output .jpg image:

Grayscale image where pixel values are scaled based on the matrix.

🔧 Requirements

• Python 3.7+
• scipy
• numpy
• Pillow
